ABSTRACT
BACKGROUND: In adolescent with intellectual disability, the management of obesity is a crucial issue, yet also quite complex because of their particular perception of themselves. This study investigated the relationship between self-perception variables and morphological variables and their changes after a 9-month Adapted Physical Activity (APA) programme. MATERIALS AND METHODS: Twenty-three adolescents with intellectual disability responded to an adapted questionnaire, including the PSI-VSF-ID and a nine-drawing body silhouette scale. Anthropometric and body composition indicators were measured before and after the APA programme. RESULTS: The main predictor of the adolescents' self-perceptions was the inclination towards positive illusory bias before the intervention; obesity awareness ranked second. Morphological measurements did not contribute in the same way to self-perceptions in the initial and final data. CONCLUSIONS: This study confirms the interest of weight management programmes for adolescents with intellectual disability and points to the need to take positive illusory bias more fully into account in the study of self-perception.

BACKGROUND: This study investigated health-related fitness in adolescents with intellectual disabilities and analysed the various performances in physical fitness tests according to degrees of obesity. MATERIALS AND METHODS: Eighty-seven French intellectual disabilities adolescents (14.24 ± 1.48 years) performed the EUROFIT physical fitness test battery. Height, weight and waist circumference were assessed, and BMI and waist-to-height ratio were calculated. 'Bio-impedancemetry' evaluated body fat (BF) percentage. RESULTS: Ninety-four per cent of the adolescents completed the aerobic running test, 52% of which had low VO(2max). Thirty-seven per cent were obese (%BF), and 32% had excess visceral adipose tissue. Adolescents with the lowest cardiorespiratory fitness had the highest BF percentages (P < 0.001). CONCLUSIONS: Intellectual disabilities adolescents showed low physical fitness and high prevalence of obesity. Both could further worsen social participation and health status.

Physical activity has been shown in large cohort studies to positively impact survival in cancer survivors. Existing randomized controlled trials showed a beneficial effect of physical activity on physical fitness, quality of life, anxiety and self-esteem; however, the small sample size, the short follow-up and the lack of standardization of physical activity intervention across studies impaired definite conclusion in terms of survival. Physical activity reduces adiposity and circulating estrogen levels and increases insulin sensitivity among other effects. A workshop was conducted at the International Agency for Research on Cancer in April 2011 to discuss the role of physical activity on cancer survival and the methodology to develop multicentre randomized intervention trials, including the type of physical activity to implement and its association with nutritional recommendations. The authors discuss the beneficial effect of physical activity on cancer survival with a main focus on breast cancer and report the conclusions from this workshop.
